From: Lev Stipakov <l...@openvpn.net>
This set of patches adds support of wintun kernel driver
(https://www.wintun.net) to OpenVPN.
While wintun is in beta, it performs significantly faster comparison to
tap-windows6.
Here are some performance numbers (download bandwidth):
Server - community openvpn2
mingw, tap-windows6 - 340Mbit/s
mingw, wintun - 675Mbit/s
VS2019, tap-windows6 - 425Mbit/s
VS2019, wintun - 750Mbit/s
Server - propietary openvpn3 with kernel acceleration (in development)
mingw, tap-windows6 - 360Mbit/s
mingw, wintun - 840Mbit/s
VS2019, tap-windows6 - 430Mbit/s
VS2019, wintun - 1,14Gbit/s
And for the reference
openvpn3 test client, VS2019, wintun - 1,71Gbit/s
Some observations from those numbers:
* wintun performs more than twice faster comparison to tap-windows6 agains
community server (750Mbit/s vs 340Mbit/s)
* Visual Studio provides noticeable performance boost (up to 25%)
* we should build Windows clients with VS, not with mingw
* There's room for improvement in openvpn2, since under best conditions
openvpn3 performs 50% faster
Steps to try out new client:
* Install Wintun driver
* since driver is not signed, you need to enable test mode to install
unsigned driver
* run in administrative command prompt:
bcdedit /set testsigning on
* restart
* download and unpack
https://staging.openvpn.net/openvpn2/wintun-0.6-unsigned.zip to C:\Temp\wintun
(for example)
* if you have OpenVPN GUI client installed, run under administrative
command prompt:
c:\Program Files\TAP-Windows\bin>tapinstall.exe install
c:\Temp\wintun\wintun.inf wintun
* alternatively you can install driver via windows device manager ->
action ->add legacy hardware -> install manually ->
point to wintun.inf in C:\Temp\wintun
* Install openvpn client with wintun support
* download and unpack
https://staging.openvpn.net/openvpn2/openvpn2-wintun-support.zip to
C:\Temp\openvpn (for example)
* if you use OpenVPN GUI, copy all files from C:\Temp\openvpn to
C:\Program Files\OpenVPN\bin. Don't forget to
stop OpenVPN Interactive Service before copying and start it back
afterwards (net stop/start OpenVPNServiceInteractive in admin command prompt)
* Connect to VPN from command line
* run from administrative command prompt
c:\Temp\openvpn>openvpn.exe --config client.ovpn --windows-driver
wintun
* you should see something around these lines in log
